At the BAU 2023, dormakaba, provider of access solutions, presented the new Door Efficiency Calculator for the first time. The energy calculator compares different dormakaba automatic doors in terms of energy efficiency, costs and CO² footprint. It takes into account the type of building, the usage and the frequency of people.

The energy efficiency of doors is an important factor in reducing energy and operating costs and minimising the carbon footprint. dormakaba’s goal is to help customers find energy-efficient solutions that meet the requirements of the respective building and its use.

The energy calculator is used as a sales-supporting consulting tool and enables a fact-based comparison and analysis of different solution variants. After entering the essential information on the type of building, the usage and the frequency of people, the energy calculator shows the differences between the compared systems and therefore allows the best solution approach to be selected. The calculator takes into account various aspects, such as the geographical location and its climatic conditions, as well as the energy sources used to heat and air-condition the building. The calculation result is summarised in a customer-specific report that shows the ecological and economic aspects of the compared input solutions.

“Our automatic doors are already known for their high quality and durability. The energy calculator also makes it possible to select the most energy-efficient solution for each building,” says Thomas Irrgang, Business Owner for automatic doors at dormakaba.
